Master Yoda’s escape from Kashyyk was going to be focussed on in more detail in Lost Jedi as he tries to make his way to the launch point with Chewie. On the far side of the planet, a contingent of Jedi are heading towards the main battle site with the intention of extraction and damage control. Yoda is aware of their presence and does what he can to aid them from his position but to no avail.
